Heather Mills teamed up with vegetarian group VIVA to point up the use of farrowing crates, as part of a campaign to highlight alleged animal cruelty. Crates are used for sows when they are giving birth and suckling their piglets. They are so narrow that the sows cannot turn around. There is an escape area at the bottom which allows piglets to run out and avoid being trampled by their mothers.
Of course it didn’t take that long for video to appear online so if you’re interested in seeing Heather breaking into pig farm you can view it here.
